オンプレのネットワーク機器のメトリクスをCloudWatchで表示できない

AWSにAmazonlinux2のインスタンスを構築して
オンプレのネットワーク機器に対してcollectd-snmpで情報収集を行い
CloudWatchに連携検討しています。

CloudWatchのメトリックス
すべて-collectd-Host,PluginInstancenを確認したところ、Host部分にsnmp.confのHostの設定ではなくインスタンス名が表示されてしまいます。
ここにsnmp.confのHostの設定を表示させるにはどのようにすればよいかご協力をお願い致します。

/etc/collectd.d/snmp.confの設定

LoadPlugin snmp
<Plugin snmp>
  <Data "uptime">
    Type "uptime"
    Table false
    Instance ""
    Values "DISMAN-EVENT-MIB::sysUpTimeInstance"
  </Data>
   <Data "std_traffic">
       Type "if_octets"
       Table true
       Instance "IF-MIB::ifDescr"
       Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"
   </Data>
  <Host "net-01">
    Address "192.168.2.XXX"
    Version 2
    Community "SysSNMP"
    Collect "uptime" "std_traffic"
    Interval 60
  </Host>
  <Host "net-02">
    Address "192.168.2.XXX"
    Version 2
    Community "SysSNMP"
    Collect "uptime" "std_traffic"
    Interval 60
  </Host>
  <Host "com-01">
    Address "192.168.1.XXX"
    Version 2
    Community "SysSNMP"
    Collect "uptime" "std_traffic"
    Interval 60
  </Host>
</Plugin>

【追記】
ここまでの手順とCloudWatch Agentの設定ファイルの内容を記載します。
0. CloudWatch用ロールの作成
AmazonEC2RoleforSSM
CloudWatchAgentAdminPolicy
CloudWatchAgentServerPolicy
0. EC2構築（Amazonlinux2）ロール割り当て
0. CloudWatch Agentのインストール
sudo yum install amazon-cloudwatch-agent
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard
0. collectdのインストール
sudo yum install -y collectd
sudo yum install -y collectd-snmp
0. collectd の CloudWatch 用プラグインをインストール
git clone https://github.com/awslabs/collectd-cloudwatch.git
cd collectd-cloudwatch/src
sudo ./setup.py

/etc/collectd.d/snmp.confの設定（上記内容）
